A waterproof goggle is provided which includes a frame, a lens and a supporting structure. The frame has an inner ring surface, an outer ring surface which is opposite to the inner ring surface and a plurality of convex engaging teeth which are disposed on the inner ring surface. The lens is surrounded by the inner ring surface and has a non-porous rim portion which is clamped by the convex engaging teeth to affix the lens into the frame. The supporting structure has a covering portion and a supporting portion which extends backwards from the covering portion. The covering portion encapsulates the inner ring surface, the convex engaging teeth and the non-porous rim portion to render a gap between the inner ring surface and the non-porous rim portion waterproof
